Answer: The odd one one is diphtheria

Explanation:

There are very minute living organisms that are able to cause different diseases to human which are found in our environment. These are known are microorganisms. They include:

--> viruses

--> bacteria

--> fungi

These microorganisms are able to establish an INFECTION in its human host when it's able fight and overcome the body defence mechanism of the host.

Diphtheria is the odd one because it's an infection which is caused by BACTERIA organism while other options while includes measles, mumps and polio are caused by VIRUS microorganisms.

BACTERIA are the larger microorganisms with a very simple cell structure where the nucleus is not enclosed within a membrane. While VIRUS are the simplest and smallest microorganisms which do not have a cell structure.

Diphtheria is an infection caused by the bacteria microorganism known as the Corynebacterium diphtheriae. These bacteria are able to produce toxins which is its virulent factor that are poisonous to its host.

Measles is an infection caused by paramyxovirus.

Mumps is an infection caused by mumps virus

Polio is an infection caused by picornavirus.

Therefore, Diphtheria infection is the odd one out.

Answer:

The moving of water causes erosion, deposition and much more!

Explanation:

Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.

Answer:

The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

Answer:

Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities.  A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.

Explanation:

Food webs in an ecosystem involves the combination of two or more food

chains. This involves all the relationship an organism has with the others.

This makes the food web complex.

Food webs have different types of organisms present which ranges from

plants which are regarded as the primary producers to animals such as Lion

which can be regarded as a Secondary/tertiary consumer in the ecosystem.

The occasional change in the geography and seasons in the ecosystem

also makes it very complex as some animals exhibit different traits when

subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.

biodiversity provides functioning ecosystems that supply oxygen, clean air, and water, pollination of plants, pest control, wastewater treatment, and many ecosystem services. seeing as how biodiversity is the basis of agriculture and our food systems. agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility, conservation of biota, and pollination of plants, all of which are essential for food production and for human survival.

Answer:

C. the parents of the big family

Explanation:

In biology, an organism that produces as much offspring is said to have a higher fitness compared to its counterpart. It is said to be biologically fit than the rest.

Therefore, in the same vein, the parents that has the biggest family is the most biologically fit of the three families.

Answer:

C

Explanation:

Skeletal muscle cells use Adrenergic receptor to receive signals from somatic lower motor neurons ; ( C ) Adrenergic

Skeletal muscles are organs of the muscular system found in vertebrates. they are attached to the skeletal bones through tendons. they all posses the longest of all muscles cells as well.

Skeletal muscles receive signals from somatic lower motor neurons through the Adrenergic receptor found in all cell and tissues .

Hence we can conclude that skeletal muscle cells use Adrenergic receptor to receive signals from somatic lower motor neurons.

The C7 spinal nerve

Explanation:

The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.

Explanation:

Answer:

The average amount of atropine in the new population will be 32 units of atropine.

Explanation:

To answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.

• We can get the selection differential, SD, by getting the difference between the mean value of the population´s units of atropine, PoUA, and the mean value of the parents´ units of atropine, PaUA. So, in this example the selection differential is:

SD = PoUA - PaUA    

SD = 10 - 50  

SD = - 40    

• The heritability in the narrow sense, h², for units of atropine in the population is

h² = units of atropine of the offspring average/selection differential

But we already know the value of h² = 55% = 0.55. And we want to know the units of atropine of the offspring. So we just need to clear the following equation.

OUA = PoUA + h² ( PaUA - PoUA)

where,  

• offspring average units of atropine = OUA

• population average units of atropine = PoUA = 10 units

• parents average units of atropine = PaUA = 50 units

• Selection diferential = SD = -40 units

• narrow sense heritability = h² = 0.55

OUA = PoUA + h² ( PaUA - PoUA)

OUA = PoUA + h² (SD)

OUA = 10 + 0.55 x ( 50 - 10)

OUA = 10 + 22

OUA = 32 units.

Answer:

d. partially permeable

Explanation:

The cell membrane is the cellular organelle that covers and bounds all cells. It forms a boundary around a cell, protecting all other organelles. The cell membrane, according to the FLUID MOSAIC MODEL, contains phospholipid bilayer, proteins etc.

The phospholipid (lipid) content of the cell membrane confers its ability to be SELECTIVELY OR PARTIALLY PERMEABLE upon it. It is said to be partially permeable because it allows the passage of some molecules/substances and blocks the passage of others.

Membrane proteins can allow hydrophilic molecules to pass through the cell membrane.

Explanation:

Answer:

Explanation:

Membrane proteins are common proteins that are part of, or interact with, biological membranes. Membrane proteins fall into several broad categories depending on their location. Integral membrane proteins are a permanent part of a cell membrane and can either penetrate the membrane (transmembrane) or associate with one or the other side of a membrane (integral monotopic). Peripheral membrane proteins are transiently associated with the cell membrane.

Answer: A

Explanation:

The statement which best describes how the clouds eventually become stars is that— “The clouds eventually collapse under the force of gravity”. Hence, the correct option is A.

Star are huge celestial bodies that are formed by the vast clouds that exist in interstellar space. These clouds are mainly composed of hydrogen and helium gas as well as small amounts of heavier elements such as carbon, nitrogen, and oxygen.

Overtime, the clouds begin to collapse under their own gravity and as they do, they become denser and more compact. As the cloud collapses, it begins to spin and then flattens into a disc-like shape. This disc becomes the birthplace of new stars.

The process of star formation is not simple and straight forward. Hence, the first step of formation of stars is the cloud collapses under its own force of gravity. Therefore, option A correct.
